Best ResponseYou've already chosen the best response.0You multiply 7 with x and 2, and 3 with x and 2, and 5 with x and 6. Then you get 7x14+3x+6 = 5x30, now you just isolate x

Best ResponseYou've already chosen the best response.0Please expand the brackets first :) 7(x2) is actually 7x14 3(x+2) is actually 3x+6 5(x6) is actually 5x30 So we would have (7x14) + (3x+6) = (5x30) Do you understand this step?

Best ResponseYou've already chosen the best response.0Then we can expand it furthermore: (7x14) + (3x+6) is actually (7x14+3x+6) Therefore (7x14+3x+6)=(5x30)

Best ResponseYou've already chosen the best response.0Now we can group the terms with "x" on the Left Hand Side, and the terms without on the Right Hand Side: 7x+3x5x = 30+146
